Vim li no muaj 3 sigma (σ) bonds thiab 2 pi (π) bonds hauv ethyn.
Ntau npaum li cas tag nrho sigma daim ntawv cog lus thiab pi daim ntawv cog lus nyob hauv ethyl acetylene CH CH)?
deb ntawm lwm cov pa roj carbon atom, peb tuaj yeem txuas ib qho yooj yim hydrogen atom, siv nws 1s atomic orbital los sib tshooj hauv daim ntawv cog lus sigma raws li kev sib koom ua ke (ib daim ntawv cog lus ib txwm yog sigma daim ntawv cog lus). sab saum toj thiab hauv qab pem hauv ntej thiab nram qab Ethyne muaj tsib tag nrho daim ntawv cog lus: peb sigma daim ntawv cog lus thiab ob daim ntawv cog lus pi
Muaj pes tsawg sigma thiab pi bonds muaj nyob rau hauv ethylene thiab cyclohexene?
In cyclohexene muaj 6 C-C sigma, 10C-h sigma bonds thiab 1 C-C pi bond.
Muaj pes tsawg sigma thiab pi bonds muaj nyob rau hauv ethylene thiab acetylene?
Acetylene tau hais tias muaj peb daim ntawv cog lus thiab ob daim ntawv cog lus pi.
Puas yog daim ntawv cog lus pi tsis muaj daim ntawv cog lus?
A pi daim ntawv cog lus tuaj yeem muaj nyob nruab nrab ntawm ob lub atom uas tsis muaj cov txiaj ntsig sib txawv ntawm lawv. Hauv qee cov hlau complexes, pi kev sib cuam tshuam ntawm cov hlau atom thiab alkyne thiab alkene pi antibonding orbitals tsim pi-bonds.
